# Science Objective: Understanding Energy Transport by Alfv\'enic Waves in Solar Flares

## TL;DR

This paper investigates the role of Alfvénic waves in transporting energy during solar flares, comparing their significance to electron beams and exploring their contribution to flare dynamics.

## Contribution

It introduces a comprehensive analysis of Alfvénic waves as an alternative or complementary energy transport mechanism in solar flares.

## Key findings

- Alfvénic waves are generated during post-reconnection relaxation.
- Energy transport by Alfvénic waves may be significant in certain flare phases.
- Electron beams are not the sole mechanism of energy transfer in flares.

## Abstract

Solar flares are driven by the release of magnetic energy from reconnection events in the solar corona, whereafter energy is transported to the chromosphere, heating the plasma and causing the characteristic radiative losses. In the collisional thick-target model, electrons accelerated to energies exceeding 10 keV traverse the corona and impact the chromosphere, where they deposit their energy through collisions with the much denser plasma in the lower atmosphere. While there are undoubtedly high energy non-thermal electrons accelerated in flares, it is unclear whether these electron beams are the sole mechanism of energy transport, or whether they only dominate in certain phases of the flare's evolution. Alfv\'enic waves are generated during the post-reconnection relaxation of magnetic field lines, so it is important to examine their role in energy transport.
